Prague Spring and Czechoslovakia 1968

It's 1968. The government next door has loosened the rules, but it's staying inside communism. You run the Soviet Union. Do you shrug, or send in the troops?

History · Czechoslovakia, 1968

Why did Moscow decide to intervene?

Stand in Moscow in 1968. Seven things are in play. Use the two menus to link the ones that fed into each other (which factor led to which?) until you can explain the decision to intervene. Then compare with the lesson's web.

  1. Slowing economy and cracks in the communist consensus
  2. Dubcek replaces Novotny and reforms begin
  3. Censorship ends and policies can be debated openly
  4. Reformers against conservatives, with Dubcek struggling for control
  5. Moscow remembers the Hungarian uprising of 1956
  6. Fear that other satellite states and Soviet Republics will follow
  7. Moscow decides to intervene (outcome)

    Evidence 2: does it support or challenge the claim?
  3. The invasion delayed the splintering of Eastern European communism.

    Evidence 3: does it support or challenge the claim?
  4. It was concluded without provoking any direct intervention from the West.

    Evidence 4: does it support or challenge the claim?
  5. In the years that followed, the new leadership improved economic conditions, removing one source of revolutionary fervour.

    Evidence 5: does it support or challenge the claim?
  6. Small-scale resistance continued throughout early 1969, and the Soviets struggled to install a stable government.

    Evidence 6: does it support or challenge the claim?
  7. The invasion temporarily derailed progress toward détente between the Soviet Union and the United States.

    Evidence 7: does it support or challenge the claim?

WHAT YOU'VE LEARNED

A quick recap of today's lesson.

Why Moscow crushed a reform that never left communism

What you need to know

  • New leaders in Prague began reforms in the 1960s to soften how communism was applied inside Czechoslovakia.
  • The economy had been slowing since the early 1960s, and cracks were showing in the communist consensus.
  • Dubcek replaced Novotny in early 1968, and his government ended censorship so policies could be debated openly.
  • April's reform plan tried to liberalise within the Marxist-Leninist framework. It did not propose a revolutionary overhaul.
  • Have a goIn your own words: what's the difference between liberalising within a system and a revolutionary overhaul of it?

    Liberalising loosens the rules but keeps the system. An overhaul would replace the political and economic systems.

    The April plan was the first kind, which is why it was not a plan to end communism.

  • Reformers clashed with conservatives alarmed by how far liberalisation had gone, and Dubcek struggled to keep control.
  • Recalling Hungary in 1956, Moscow feared other satellite states might follow, and that Soviet Republics might demand more liberal policies.
  • Have a goYour mate insists Hungary's 1956 uprising was copying Prague. Check their calendar: which came first, and what does that mean for Moscow's fear?

    Hungary came first, in 1956. Moscow recalled it and feared a repeat, with others following Prague.

    1956 is the memory shaping Moscow's worry in 1968; it can't be a copy of something twelve years later.

  • After much debate, Moscow decided to intervene and install a more conservative, pro-Soviet government in Prague.
  • On 20 August 1968, Soviet-led Warsaw Pact troops invaded and swiftly took control of Prague, other major cities and key links.
  • The Soviets guessed correctly that the US would condemn the invasion but not intervene, given Vietnam and earlier non-intervention statements.
  • Afterwards, the Brezhnev Doctrine justified the force: Moscow could intervene wherever a communist government was threatened.
  • Have a goA friend writes: 'Moscow invaded because of the Brezhnev Doctrine.' Spot what's wrong with that sentence.

    The doctrine came after the invasion, to justify force already used, so it can't have caused it.

    A justification given afterwards can't be a reason for acting beforehand. The reasons are the pressures and fears in the web.

The big picture

In 1968 Czechoslovakia tried to loosen communism from the inside. Moscow crushed it anyway, because of what the reforms might start elsewhere. This lesson builds the web of pressures and fears behind that decision, then follows the invasion's consequences all the way to Afghanistan.

Key points

1The Prague Spring reformed communism from the inside. It did not try to replace it.
2Moscow's fear was contagion: Hungary 1956 remembered, with satellite states and Soviet Republics possibly following.
3On 20 August 1968 Soviet-led Warsaw Pact troops took control swiftly, and the US condemned but did not intervene.
4Success had costs: resistance into 1969, a struggle to install a stable government, and derailed détente.
5The Brezhnev Doctrine justified the invasion afterwards, then helped finalise the Sino-Soviet split and justified Afghanistan in 1979.

⚠ Watch out

Don't call it a purely Soviet invasion. The Soviet Union led Warsaw Pact troops, with limited numbers from Hungary, Poland, East Germany and Bulgaria alongside troops from the Soviet Union.

🧠

Memory hook

Look from Moscow's window. Not 'what did Dubcek want?' but 'what happens if everyone copies him?'
